Super Reaction Rod by efn31, February 18, 2019
Geissele is usually known for their triggers. Sometimes people forget that they make tools as well. I've found this tool to be most helpful with builds and it can help prevent damage to parts. Don't waste your time with other brands. Stick with t...

Hard to Improve on This by Kevin, Verified Owner, March 23, 2020
The reaction rod is good. The Super is better. When torquing a barrel nut or breaking loose a tight one the Super with the little dogs in the ejector port hold the receiver so the little pin on the barrel extension and the slot in the receiver don't...

Works great by John Moses, Verified Owner, August 24, 2019
Works great! Hold the upper firmly and allows you to torque anything in or break anything off as needed. Doesn’t make any marks on the uppers ejection port. Works for LH eject as well. No complaints other than it’s expensive.

Good tool for a builder by Paulo, May 30, 2017

Rection Rod by Bob, June 9, 2019
An absolute must have for barrel and upper work on your AR-15. Takes ALL of the pressure away from the upper. Fits into the barrel extension and then secures the upper with two non marring bronze wedges which keep the upper from moving. Hole the uppe...

Product Info for Geissele AR-15/M4 Super Reaction Rod

Designed with the advanced armorer in mind, an armorer who frequently works on AR15/M4 platforms with over torqued, seized or Loctited barrel nuts. Works by pre-loading the barrel nut extension to the lugs of the Super Reaction Rod to eliminate any movement before adding torque to the barrel nut, while at the same time fixing the upper receiver into place. Having the barrel nut extension mated to the Super Reaction Rod lugs and fixing the upper receiver before torqueing will remove any potential stress that could be placed on the index pin. Allows the armorer to place tremendous torque on the barrel nut. Super Reaction Rod's pre-loading system can also be removed to allow it to work just like a standard Reaction Rod, which allows upper work to be performed with 360 degree movement, both vertically, and horizontally.image
